1a. A proposed mechanism is:
1) 2 A + B → C (slow)
2) C → A + D (fast)
If this mechanism is correct, by what numerical factor should the rate of reaction increase if [A] is increased by a factor of (6.57x10^0)?
1b. A first-order reaction has a half-life of (5.30x10^1) minutes. How many minutes would it take for the only reactant to decrease to 12.5% of its initial concentration?
1c. A reaction has an activation energy of 125.0 kJ/mol. At 310. K, the rate constant is (6.09x10^-4) s-1. What would be the value of the rate constant in s-1 at 300. K?
1d. A reaction is known to follow first-order kinetics and has a rate constant of (6.260x10^-2) min-1. If the initial concentration of the only reactant is (1.44x10^0) M, what will be the concentration after (5.150x10^1) minutes?
1e. A reaction is known to follow first-order kinetics. What is the half-life (in seconds) if it takes (7.110x10^2) seconds for the concentration of the only reactant to drop from (3.790x10^0) M to (3.83x10^-1) M?
Will rate. Due in 30 min, Please answer it all. Thank you.

(2) Let Z/nZ be the set of n elements {0, 1, 2, . . . , n ? 1} with addition and multiplication modulo n. (a) Which element of Z/5Z is the additive identity? Which element is the multiplicative identity? For each nonzero element of Z/5Z, write out its multiplicative inverse. (b) Prove that Z/nZ is a field if and only if n is a prime number. [Hint: first work out why it’s not a field when n isn’t prime. Try some small examples, e.g. n = 4, n = 6.]
